(CNN) – As Sen. Barack Obama ends the primary process and begins his transition from Democratic front-runner to presumptive nominee, a new Gallup poll suggests that his bid to win over the support of his party’s white and Hispanic women voters is far from over.
Even with her presidential bid all but formally over, Sen. Hillary Clinton edges Obama slightly among female Democratic voters overall, with a four point lead; the New York senator has the support of 49 percent of Democratic women while Obama has support from 45 percent, according to Gallup.
Although Obama lags Clinton by only four percentage points among female Democrats overall, his problems with white and Hispanic women are much deeper.
Clinton leads Obama by 20 percent among white, female Democrats: She has the support of 57 percent of white women Democrats, while Obama's support stands at 37 percent.
Among Hispanic women who are Democrats, the difference in support is even larger. Sixty-two percent of Hispanic women who are Democratic voters support Clinton, and Obama lags by 30 percentage points, with support from just 32 percent of the demographic.
Obama’s troubles with working class voters are also a factor in the equation: 62 percent of female non-college-educated white Democrats support Clinton, while 32 percent of the same group supports Obama - but among white, college-educated women Democrats, Clinton and Obama are virtually tied – 48 percent to 47 percent.
Obama’s problems with seniors also play a role:Among white, female Democrats aged 65 or older, Obama loses out to Clinton by 36 percentage points - 64 percent of that core Clinton constituency support her, while only 28 percent support Obama. Among younger white women voters, that gap narrows considerably. Obama has a 12 percentage-point lead with white, female Democrats aged 18 to 29.
The Gallup survey released Tuesday is based on telephone interviews of 12,151 national Democratic voters, aged 18 and older. The poll was conducted May 1-May 31 and has a margin of error of plur or minus two percentage points.
